Hope my answer helps!!
Answer:
B
) Negative
Step-by-step explanation:
Given the expression 3xy
when x>0 and y<0
The value of the expression 3xy will be negative.
This is because the product of a positive and negative number will always be negative.
For illustration,
Let x=5>0 and y=-5<0
3xy=3(5)(-5)=-75

Multiply 72×80 or 8. (I'm not sure of its 8 or 80).HOPE THIS HELPS YOU:)
<2 = 45 degrees They are corresponding angles
74 + <1 + <2 = 180 it makes a straight line
74 +<1 +45 = 180
119 +<1 =180
subtract 119
<1 = 180 -119
<1 = 61 degrees
